The Shuttle Radar Topography Mission (SRTM) fly casting technique is designed to minimize structural loading of the 60-meter extendible boom antenna during the STS-99 mission in September. During this experiment, Columbia's crew will conduct a sequence of orbiter jet firings that will minimize the dynamics of the orbiter during trim burns. This investigation of the optimum settings and timing of trim burns must be conducted--before the flight of the SRTM--to verify the on-orbit feasibility of the ground-developed technique. Only one flight of this experiment is planned.
